SDHC is a new format for 4GB SD (and miniSD) cards. It won't work in our phones.
somehow i completely missed this thread when I asked my question. Could have easily got my answer before I asked. Way to screw up my first post. Looks like i'll just stick with a 2gb card.
I bought a 4gb mini SD from EBAY because I thought I got a bargain at $30 and was hoping I could have the luck some of you have had.
Unfortunately, when trying to put 4gb worth of data on there - the card has lost all of it's formatting several times. Right now, it still shows a 4gb capacity - but says 600 megs is already used up, when the card is empty. Right now I'm wishing I'd spent an extra $17 for the TopRam version instead of the Generic - but I think that'd be a gamble as well.
I'll keep trying to reformat this thing, but for now - I'm regretting my purchase.
Back on 2/16/07 I said I was buying one of the 4g mini sd cards and giving it a try. Well, I did, and it's still going strong 3 months later. I had to reformat it during a vacation when I needed the space for digital pics, but was able to reload my music and get everything hooked back up.
I use PocketMusic as my player, and I've installed it onto the SD card instead of the 6700 itself. I have 3.5G of music on the card and it plays well. However, PocketMusic takes a long, long time to open and/or manipulate playlists. I don't know if it's because the music is all stored on a slow card (fast enough to play without skipping, however) or if it's because the app is on the card too. Sometime soon, I may move things around and put the app on the 6700 itself just to see.
For now, I have lots of tunes, no reason to carry my ipod, and integration with my bluetooth headset (btaudio) for those times where I just want a little background music in my head.
I do find that I need to jack-in at the office as playing music sucks the battery dry, but that has very little to do with the card.
While my generic sucked badly - I was able to return it, so I was only out shipping. I then got a TOPRAM 4gb card - and have had very good luck. In the 2 months since I've had it, I've only had to reformat once because some data got corrupted. But otherwise, it's running strong.
I've got maps for GPS, movies, music and video games on there. I'm crossing my fingers that this card will stay reliable, but Topram has good warranty service. They were going to accept my old card for repair until I figured out how to reformat it - in a Treo of all things.
I have the generic Ebay one. In the past 3-4 weeks it has not gone down again. I am very careful now to keep a backup of what is on the card, on my PC hardrive as well...so all it takes is a quick format and recopy the files over in order to get back up and running.
I was about to ditch it and go to a 2 GB card....but have since decied to live with the uncertainty and keep using the 4gb with the PC backup.
I keep Hubdog and Weather panel loaded as main memory and all other programs on the card...the only daily issue I see is that the icons (if placed in the startup/first seen/menus selction place) seem to not appear upon a soft reset...though they still work fine. If you browse to them in file explorer, they seem to come back. The first time I did this I about had a heart attack as this is the same behavior that lets you know your card has been dorked again by data corruption....The missing Icons only seem to happen to the programs that are on the memory card AND are selected to appear right away in the "menu".
I keep hoping someone will come out with an official 4 gb MiniSD (non-SDHC) at some point that works better....but until that happens I will live with my occasionally buggy generic one...with regular backups. When a new Sprint PocketPC comes out with SDHC support, I will likely switch to it.
From what I have gathered it is not likely. Apparently the SD standard relies on a onboard memory controller and so you must have this new onboard memory controller on your device in order to use the SDHC. Interestingly the COmpact Flash cards all have their controllers on the actual card...so the reason we see no problem with 16 GB cards and higher on many old devices.

I've read that - but then again, I'm surprised that my roommate has used a firmware update for his Treo 650 to use SDHC cards. The Treo 650 is older than the 6700 - so I'm surprised it would have the updated memory controller. He's been using an 8 gig SDHC card for months now.
I know this my seem odd and I could be 100% wrong but does anyone’s 4GB or larger SD Mini card have the SD Card Association’s logo (not the letters “SDHC” but the logo that shows SD above HC) and/or 2, 4, or 6 inside the letter “C”. This means 2MB, 4MB or 6MB per sec sustained transfer rate.
I believe these are the cards that WILL NOT work because the SD Card Association states that they are not backward compatible (inside they are completely different).
I also believe the card manufactures that are not using the SD Card Association’s standard are each off on their own tangent and that is why some cards work and others do not.
The above information is correct to an extent. It only applies to the SD memory card (sorry). There are no standards for MiniSD High Capacity cards at all. So… the previous paragraph still fits.

Hey Polloloco,
did you get your topram 4g card on ebay ? I saw one one there for like $35 or something and wondered if it was the real deal and how it worked
Yeah, I got the 4gb TopRam card on EBAY. I contacted TopRam directly - and was told that only vendors on EBAY sold the 4gb version.
I had such good luck with the 2gb version that I felt TopRam was a good company.
The 4gb card works well. But periodically after about a month of extensive use, I usually have to reformat and start over. Either a file gets corrupt, or they all do. So I backup to my computer regularly. The generic card I first got didn't work even this well.
Unlike the generic, the TopRam never seems to get TOTALLY unusable. The generic got corrupt as soon as I went over 2gb.
Polloloco, thanks for the reply. Hmmmmm, thats still a drag about having to reformat once a month. How longs that take ?? Do you just keep everything in one folder on your PC and then just copy it back over to the card? Can you run apps off the card ?
The 4 gig I had worked OK *as long* as I loaded everything from my PC and kept things at the top level. As soon as I tried deleting or messing around with stuff on the 4 gig through the PocketPC it destroyed the card.
So it isn't supported, albeit you can get it to work.
This TopRam has worked well for me so far. Both copying to through pda and pc/activesync, installing, deleting, ect... Only problems I've encountered is when installing apps that auto-refresh or load off the today screen such as weatherpanel, wisbar, ect... Other than that, for extra storage of vids, music, games, programs only accessed on demand, it has so far worked flawlessly.
OK, thanks for all the info. I just ordered the 4G TopRam off Ebay.
I'll letchyas all know how it works . Before that, I was searching 4G MicroSD cards, figgerin on thats what my next future some day device will use, but didn't have much luck. Anyone ever come across any?
